Optus

Optus is Australia's second-largest telco and a subsidiary of Singtel, the Singapore-headquartered telecommunications group. It sells mobile plans (SIM-only, phone-on-plan, mobile broadband), home internet on the NBN and 5G Home Internet, prepaid recharges, and small-business connectivity. It also runs Optus Sport (Premier League, European football and rugby coverage), the SubHub bundle for streaming subscriptions, and the Optus Perks loyalty programme. Activate ShopBack Australia at shopback.com.au/optus before clicking through so eligible sign-ups earn cashback at the current published rate.

Optus sells SIM-only postpaid plans across small, medium, large and XL data buckets, phone-on-plan bundles that finance a handset over 12, 24 or 36 months, and mobile broadband for tablets and hotspots. Larger plans typically bundle Optus Sport and a SubHub credit; smaller plans focus on data and included international minutes. Verify current inclusions and pricing on optus.com.au before locking. Activate ShopBack Australia at shopback.com.au/optus first so eligible plan sign-ups earn cashback at the current published rate.

Optus Prepaid runs three main shapes: daily, weekly and 28-day (monthly) recharges, plus a longer-term Choice Plus option for users who want to lock in a bigger data bank for a set price. Choice Plus tiers typically include unlimited standard national talk and text with a data bucket that lasts across the plan period. Prepaid is a good fit for shoppers who want month-to-month billing with no fixed-term contract or who share plans across a household. Confirm current recharge prices and inclusions on optus.com.au before locking.

Optus retails NBN across the standard speed tiers, typically NBN 25 (Basic II), NBN 50 (Standard Plus), NBN 100 (Premium), NBN 250 (Home Fast), and NBN 1000 (Home Ultrafast) where the connection type supports it. Home Fast and Home Ultrafast are only available on FTTP or HFC lines that meet the throughput criteria, so the tier you can actually order depends on your address. Optus 5G Home Internet is a fixed-wireless alternative in eligible suburbs and can be a strong pick where the NBN copper leg is slow. Verify tier availability by address on optus.com.au before locking.

Optus Sport is a subscription streaming service focused on Premier League, European football and rugby coverage, and it is typically included with selected Optus mobile and home internet plans (verify current rights and inclusions on optus.com.au). Optus SubHub is a bundling engine that lets you pay for multiple third-party subscriptions (Netflix, Disney+, Paramount+ and others) in one Optus bill with a small stacking discount when you bundle two or more services. SubHub is useful for households already paying for multiple streaming services separately who would rather consolidate the bill and lift a small saving. Verify current SubHub partners and discount mechanics on optus.com.au before signing up.

Optus Perks is the loyalty layer inside the My Optus app, offering rotating rewards like movie ticket discounts, coffee vouchers, retail credits and occasional food or delivery offers to eligible Optus mobile and home internet customers. It is a low-effort loyalty layer, most useful if you already spend on the categories in the current perks refresh. Perks are stacked on top of any base plan and do not typically require a code; they surface directly in the app.

Telstra is typically the pick for shoppers in regional and rural Australia because of its wider Outback and highway coverage footprint, though this typically comes at a price premium on comparable mobile plans (verify current pricing on telstra.com.au). Optus is the stronger price-to-coverage balance in metro and major regional centres, and it wins on entertainment bundle value (Optus Sport plus SubHub credits) that Telstra does not directly match on its base plans. Pick Telstra if you regularly drive or work outside major population centres; pick Optus if you mostly use the phone in metro or coastal areas and want the Sport and SubHub layers included. See our Optus vs Telstra vs Vodafone vs TPG breakdown for a full network read.

TPG and Vodafone Australia merged and now share a single network, marketed under both brands and under felix mobile, which is TPG's low-cost MVNO. Vodafone and TPG typically undercut Optus on SIM-only pricing and lean on aggressive NBN promotional pricing (particularly on NBN 100 and NBN 250 tiers). Optus typically leads them on entertainment bundle value (Sport and SubHub) and on Perks refresh cadence. If you value bundled streaming and loyalty offers, Optus is the natural pick; if you want the cheapest usable SIM-only or NBN monthly bill, Vodafone, TPG or felix mobile are typically the sharper options. Verify current pricing on each provider before locking.

MVNOs (mobile virtual network operators) resell capacity on the big three networks at typically lower monthly prices in exchange for a lighter feature set. Amaysim runs on the Optus network and is a common pick for shoppers who want Optus coverage without the postpaid contract. Boost Mobile runs on the Telstra retail network and is the main way to access Telstra-network coverage at a discount. Kogan Mobile runs on the Vodafone network and typically sits near the lowest per-GB SIM-only price point in Australia (verify current pricing on kogan.com/au/mobile). felix mobile is TPG's MVNO on the Vodafone/TPG network with a single-plan structure and an environmental positioning. Optus retail plans win over these MVNOs when you specifically want Optus Sport, SubHub credit, or Perks; the MVNOs typically win on straight-line dollar cost per month if you only need talk, text and data. Kogan Mobile has a ShopBack Australia merchant page at shopback.com.au/kogan if you want to layer cashback on the MVNO route.

Optus phone-on-plan bundles a handset (iPhone, Samsung Galaxy, Google Pixel and others) on a 12, 24 or 36-month device repayment alongside a SIM-only plan. The handset repayment is separated from the plan cost on the bill and is typically interest-free over the term. Buying the phone outright from a retailer like JB Hi-Fi or Officeworks and pairing it with an Optus SIM-only plan is usually cheaper on total spend but requires the upfront outlay. Phone-on-plan is a good fit for shoppers who want the cashflow smoothing and are willing to stay on the same telco for the device term; outright plus SIM-only is the sharper option for shoppers with cash on hand who want plan flexibility. See our JB Hi-Fi iPhone comparison at shopback.com.au/blog/finance/apple-au-vs-jb-hifi-vs-officeworks-iphone-2026 for the outright side.

Optus does not sell a formal single-line family bundle; the practical equivalent is running multiple postpaid SIM lines on one Optus account and layering SubHub for shared streaming across the household. Larger postpaid plans typically include Optus Sport and a SubHub credit that the whole household can use, so the effective family value comes from the entertainment layer rather than a per-line multi-plan discount. Households already paying for two or three streaming subscriptions separately typically get the strongest value from consolidating them under SubHub while running Optus mobile on multiple lines.

Switching between Australian telcos is a mobile number portability (MNP) process regulated by the ACMA. Sign up for the Optus plan you want, provide your existing mobile number and current provider, and Optus initiates the port. The old service usually stays live until the port completes (typically within a few hours, sometimes up to a business day). Cancel any AutoPay on the old service after the port completes to avoid a stray charge. Complete the sign-up in the same browser session as your ShopBack Australia click-through so the port is tracked as a new eligible customer for cashback.

Check address availability on optus.com.au; the checker returns your line technology (FTTP, HFC, FTTN, FTTC or Fixed Wireless) and the top NBN tier that address supports. Pick your speed tier and pay any once-off connection or hardware fee if applicable. Optus typically ships a modem-router; installation may require a technician visit for a new FTTP or HFC line. Once activated, keep the plan on the same address for the minimum cashback-eligibility window per current terms.

Optus 5G Home Internet is a fixed-wireless product on Optus 5G towers, delivered via a plug-and-play modem with no NBN co install. It can be a strong pick where the NBN line at your address is on slower FTTN copper, or where you want to skip a technician visit. Speed varies by tower distance and time of day, versus NBN which is contracted at a nominal tier. NBN is typically the more predictable pick for heavy-usage households; 5G Home is typically the sharper pick for renters, short-term addresses, or FTTN-limited streets. Verify 5G Home coverage by address on optus.com.au.

Optus typically runs its deepest annual mobile and NBN promotions across End of Financial Year (late June through July), Boxing Day, and Black Friday and Cyber Monday (last Friday of November through the following Monday). Back-to-school (January) typically brings student and family plan campaigns, and the Optus Perks refresh cadence brings rotating retail and entertainment offers throughout the year. Plan-specific promos (bonus data, waived setup fees, gift cards on sign-up) run rolling outside these headline windows. Activate ShopBack Australia at shopback.com.au/optus before clicking through so sale-window pricing is also covered by cashback on eligible sign-ups.

Optus's direct-site pricing typically applies any current campaign discount at checkout without a separate promo code, and sign-up bonuses (bonus data, waived connection fees, gift cards) are typically auto-applied to eligible plans during the promo window. Third-party voucher code sites often list expired or affiliate-referral codes that can break ShopBack cashback tracking. Stick to the discount already shown on the Optus checkout plus ShopBack Australia cashback; activate through shopback.com.au/optus before clicking through, no code required.

Sign in to ShopBack Australia, click through to Optus from the merchant page at shopback.com.au/optus, and complete the sign-up in the same browser session without switching to outside voucher codes or referral links. Cashback is then tracked against your ShopBack account, subject to the current published rate and terms on the merchant page. Eligibility is typically new-customer or new-service, and the sign-up usually needs to remain active for a minimum period before cashback confirms. Verify current tracking and confirmation windows on the merchant page before locking.

Pending cashback on Optus sign-ups typically appears in the ShopBack Australia app within the tracking window published on the merchant page, and confirmed cashback typically lands after the service remains active through the confirmation window per current Optus terms. Missing-cashback claims can be lodged within 7 days of the click-through via the ShopBack app with the sign-up confirmation. Verify the current tracking and confirmation windows on the merchant page before locking.

For metro and major regional Australian households, Optus is typically a strong price-to-coverage pick, particularly for shoppers who value bundled Optus Sport and SubHub credit alongside the mobile or NBN plan. Regional and rural shoppers typically get more coverage headroom on Telstra; cost-first shoppers typically save more on Vodafone, TPG, felix mobile, Amaysim, Boost Mobile or Kogan Mobile MVNOs. On value, an Optus plan sized to your actual data usage, timed to an EOFY or Black Friday sale window, and activated through ShopBack Australia at shopback.com.au/optus for the current cashback rate is typically the strongest net-cost route for shoppers who want Optus specifically.

Cashback tracking on Optus is tied to the web click-through from ShopBack Australia, so sign-ups completed on optus.com.au after activating the ShopBack merchant page in the same browser session are what qualifies. Sign-ups completed directly inside the My Optus app without a preceding ShopBack click-through will typically not track. The reliable route is to start on the ShopBack Australia Optus page, click through to optus.com.au, and complete the plan sign-up on the web before switching to the app for ongoing account management.

Common exclusions across Opt include gift card purchases, third-party marketplace items, in-store pickup orders, and selected sale or clearance categories. Full exclusion list is published on the ShopBack Opt merchant page terms and updates periodically.

Yes. ShopBack cashback on an Optus plan sign-up only tracks against a signed-in ShopBack Australia account, so the click-through from the ShopBack Optus merchant page is tied to your member ID. Registration is free at shopback.com.au/signup and takes under a minute. Sign in first, then open the ShopBack Optus page and click through to optus.com.au to complete the plan sign-up in the same session so the affiliate click is recorded and cashback lands in your account at the current published rate.

Yes. Optus supports eSIM activation on eligible iPhone and Android handsets across postpaid and prepaid, letting you activate the plan digitally without waiting for a physical SIM to ship. eSIM is useful for travellers layering a domestic Optus line with an international travel eSIM, and for shoppers switching networks who want to avoid a SIM-swap delay. Complete the plan sign-up through the ShopBack Australia click-through at shopback.com.au/optus so eligible sign-ups earn cashback at the current published rate, then activate the eSIM in the My Optus app after the port completes.

Optus postpaid bills run on a monthly cycle set from your activation date, with a bill issued a few days before the direct debit. You can upgrade or downgrade the plan mid-cycle in the My Optus app; upgrades typically apply pro-rata inclusions from the switch date, while downgrades usually take effect from the next full billing cycle. Prepaid recharges run independently of any billing cycle since you top up as needed. If you plan to switch to Optus from another telco, activate ShopBack Australia at shopback.com.au/optus before signing up so eligible new sign-ups earn cashback at the current published rate.

Optus sells daily and weekly International Roaming day passes that give a set data, talk and text bucket across most popular travel destinations, activated automatically when you land or manually via the My Optus app. This is typically simpler than pay-as-you-go roaming but can cost more than a local travel eSIM for longer trips. For short weekend hops to Bali, Fiji or New Zealand the day pass is usually the sharpest pick; for multi-week trips a dedicated travel eSIM alongside the Optus line is often cheaper. Verify current roaming zones and daily pass pricing on optus.com.au before departure.

Yes. ShopBack cashback on an Optus sign-up is tracked as Pending after the click-through from the ShopBack Optus merchant page and only converts to Confirmed if the plan remains active through the confirmation window published on the merchant page. If you cancel the plan inside the cooling-off period or before the eligibility window closes, the pending cashback is typically voided. Keep the service active through the confirmation window to lock in the cashback.

Start from the ShopBack Optus page in the ShopBack app, on shopback.com.au or via the ShopBack browser extension, click through fresh to optus.com.au, and complete the new-service order online in that same session without pasting codes that are not listed on ShopBack. The order shows as Pending in your ShopBack account within the 25-day tracking window listed on this page, then moves to Confirmed once the service has stayed connected for 90 days and Optus validates it, which ShopBack lists as up to 130 days. Cashback is a fixed amount per eligible new service rather than a percentage of your bill, and it is paid once per order regardless of how many plans or SIMs are on it.

As of 2026-10-04 the ShopBack Optus page carries three things. First, cashback: a fixed amount per eligible new service, shown by category on this page (nbn Home Internet excluding BYO-modem plans, 5G Home Internet, Postpaid Mobile with device and plan, Postpaid Mobile SIM only, and Prepaid SIMs at the A$39, A$40, A$49, A$59, A$180 and A$350 price points), paid after confirmation. Second, gift cards: there is no discounted Optus gift card or ShopBack swap card for Optus on the ShopBack gift card hub at shopback.com.au/gift-cards as of this date, so the stack is Optus's own promo pricing plus ShopBack cashback. Third, an upsize: none is flagged on the Optus page as of 2026-10-04; when one runs it appears as an Upsized label next to the category on this page.

Work it as first-year plan cost minus the fixed cashback amount shown on this page. On the Optus Basic nbn plan at A$68 a month for 12 months (A$816 for the year, offer ending 6 October 2026), a A$50 cashback figure used purely as an illustration would bring the effective first-year cost to A$766, or about A$63.83 a month. On the Small Choice Plus SIM promo at A$39 a month for 12 months (A$468), the same A$50 illustration gives A$418, or about A$34.83 a month. Optus cashback on ShopBack is a flat amount rather than a percentage, so the saving is proportionally bigger on cheaper plans. Read the live amount for your category on this page before you order; it is paid to your ShopBack balance after confirmation and withdrawn to your bank account or PayPal.

Yes, on new activations only. The ShopBack Optus page lists prepaid cashback by SIM price point (A$39, A$40, A$49, A$59, A$180 and A$350 Prepaid SIMs, including eSIM), and ShopBack's Optus terms require the SIM to be activated within 28 days of purchase and to stay in an active recharge state for 90 days after activation. Optus's own prepaid range on 2026-10-04 is sold as Flex Plus recharges at A$40, A$44, A$50, A$54 and A$64 for 28 days plus A$15, A$200 and A$395 long-expiry options, so match the SIM you buy to a price point listed on this page or the order may track at a lower tier or not at all. Recharges on an existing prepaid number do not earn cashback.

Optus Perks is a loyalty layer you use after the service is live, so it has no bearing on whether the sign-up tracks. SubHub credits (A$10 or A$20 a month on the A$79 and A$89 Optus Plus Promo plans as listed on optus.com.au on 2026-10-04) are plan inclusions, not discounts applied at checkout. What does void cashback under ShopBack's Optus terms is any discount that lowers the advertised price (staff, student, employee advantage, Flybuys, regional, price-matching) and any promo code not featured on ShopBack. Optus's standard in-market promo plans, such as 100GB for A$39 a month for 12 months, are the advertised price on optus.com.au; if you are unsure whether a specific deal counts as a store promotion, check the exclusions on this page before ordering.

Confirmed cashback sits in your ShopBack Australia balance and can be withdrawn to an Australian bank account or to PayPal from the ShopBack app or website. There is no minimum spend on Optus to qualify, but the amount is fixed per eligible new service and paid once per order regardless of how many SIMs or plans that order contains. Expect the Pending to Confirmed step to take up to 130 days on Optus because of the 90-day connected requirement.

The ShopBack browser extension works: activate it when you land on optus.com.au and it creates the same tracked session as clicking through from the ShopBack Optus page, with the same rules about finishing the order online in that session. Optus web chat does not work: ShopBack's Optus exclusions state that orders completed via chat are not eligible, so if a chat agent offers to place the order for you, decline and finish the self-serve checkout yourself. Do not run a VPN, an adblocker or a second cashback extension at the same time.

Optus does not run coupon codes on optus.com.au; its deals are promo plans priced in the cart. As listed on 2026-10-04: the A$60 Small Choice Plus Promo plan at A$39 a month with 100GB for the first 12 months on new services (ends 12 November 2026), a student version with 200GB for A$39, home internet from A$44 a month for 12 months across nbn, 5G and 4G (ends 6 October 2026), nbn plans from A$68, 5G Home Internet from A$54, and A$15 off for a year on each eligible nbn plan added to a mobile account. These are advertised prices, so they are the stack that works with ShopBack cashback. Third-party voucher sites listing Optus codes are the thing to avoid: any code not featured on ShopBack voids tracking, as does any staff, student, Flybuys or regional discount.

MVNOs resell the big three networks at lower monthly prices with a lighter feature set. Amaysim runs on the Optus network, so it is the pick if you want Optus coverage without postpaid and do not need SubHub or Perks. Boost Mobile runs on the full Telstra prepaid network and is the pick for regional coverage on a prepaid budget; its 28-day plans run A$28 to A$74 as of 2026-10-04. Kogan Mobile and felix mobile run on the Vodafone and TPG network and compete on per-GB price. Optus retail wins when you want 5G at no extra cost on Choice Plus, data sharing, the Family Plan, SubHub credit, or phone-on-plan financing. Amaysim, Boost Mobile, felix mobile and Kogan each have their own ShopBack pages.

As listed on optus.com.au on 2026-10-04, the Choice Plus SIM-only range is month to month with no lock-in: Small Choice Plus 60GB at A$60, Medium Choice Plus 240GB at A$70, Large Choice Plus 480GB at A$90, plus a 360GB Promo Plan at A$69. New services on the A$60 Small plan get 100GB for A$39 a month for the first 12 months (ends 12 November 2026), and students get 200GB for A$39. All include 5G access on a compatible device and Endless Data, which drops speed to 1.5Mbps after the allowance instead of charging excess. A new SIM-only sign-up through the ShopBack Optus page earns the Postpaid Mobile SIM Only cashback amount shown on this page.

Three 5G Home Internet plans are listed on optus.com.au on 2026-10-04, all unlimited data on new services with pricing for 12 months then the standard fee, offer ending 6 October 2026: Everyday 5G at A$54 then A$69 (50/11Mbps typical busy period), Everyday Fast 5G at A$64 then A$79 (87/15Mbps), and Entertainer Superfast 5G at A$84 then A$99 (230/20Mbps). A 4G Home Internet plan is A$44 then A$59 in select areas. The 5G modem is credited at A$13 a month over a 36-month device payment plan so it costs A$0 if you stay; leave early and the remaining modem balance is payable. 5G Home Internet is its own cashback category on the ShopBack Optus page.

The Optus Family Mobile Plan gives up to 4 SIMs for A$165 a month sharing 320GB, month to month, as listed on optus.com.au on 2026-10-04. Households with more than four people can add up to four Optus Plus Kids data-share SIMs at A$29 each per month, and the plan includes a safety and parental-control app subscription that normally costs A$8.99 a month. At A$41.25 per line for four lines it undercuts four separate Small Choice Plus plans at A$60 each by A$75 a month at standard pricing, though the 100GB for A$39 promo on single lines narrows that gap in year one. Cashback through the ShopBack Optus page is paid once per order regardless of the number of SIMs.

Skip Optus when coverage outside cities is the deciding factor: Telstra and Boost Mobile on the full Telstra network are the safer bet for remote travel and regional properties. Skip it when you only need a few GB a month, because an 8GB Boost plan at A$28 or a small Amaysim or felix plan costs less than Optus's A$60 entry Choice Plus plan at standard pricing. Skip the ShopBack route if you are an existing Optus customer changing plans, if you want to order via web chat or the app, or if you plan to use a staff, student, Flybuys or regional discount, because none of those earn cashback. Skip the nbn category if you bring your own modem, since BYO-modem nbn plans are excluded.

Yes, but once. ShopBack's Optus terms state cashback is paid once per order or transaction regardless of the number of plans and SIMs on that order, so a Family Mobile Plan order or a multi-SIM Choice Plus order earns a single fixed amount, not one per line. Every line still has to be a new service for a new Optus customer, and the whole order has to stay connected for 90 days before it confirms. Tablet plus Data SIM plans are excluded from cashback entirely.

Optus plan prices on optus.com.au are shown in Australian dollars with GST included, and you pay postpaid plans by direct debit from a credit or debit card or bank account after the monthly bill issues, while prepaid is paid upfront per recharge or via Auto Recharge. The online order requires ID, a credit card and employment details for a credit check. ShopBack cashback is calculated on the eligible new service and excludes GST, other taxes and delivery fees by ShopBack's terms, and paying any part of the order with an Optus gift card voids it.

No. ShopBack's Optus terms state cashback is not eligible when used in conjunction with staff or student, employee advantage, Flybuys or regional discounts, and the general exclusions cover any discount that lowers the advertised price including price-matching. Optus's own student promo plan (200GB for A$39 a month for 12 months as of 2026-10-04) is a student-verified discount, so treat it as excluded unless the ShopBack Optus page says otherwise. If the cashback amount shown on this page is worth more to you than the discount, order the standard promo plan at its advertised price instead.

As listed on optus.com.au on 2026-10-04, the cheapest ongoing Optus mobile service is the A$40 Flex Plus prepaid recharge for 28 days, while the cheapest postpaid entry is the Small Choice Plus SIM-only promo at A$39 a month for 100GB for the first 12 months (A$60 a month after, offer ends 12 November 2026). On home internet the entry point is the Basic nbn plan at A$68 a month for 12 months. To take any of them lower, start from the ShopBack Optus page, click through in the same session and complete the order on optus.com.au as a new customer; the fixed cashback amount for that category shown on this page is paid once the service has stayed connected for 90 days. On the A$39 promo plan that is A$468 for the year before cashback, so a fixed amount comes off a small base and the saving is proportionally larger than on a Large plan.

Student discounts do not stack: ShopBack's Optus terms exclude cashback used with staff, student, employee advantage, Flybuys or regional discounts, so the student plan (200GB for A$39 a month as of 2026-10-04) earns nothing on ShopBack. Optus did not publish a seniors-specific plan or discount on optus.com.au as of October 2026, so there is no seniors stack to test; a senior ordering a standard Choice Plus plan is treated like any other new customer and earns the amount shown on this page. Bundles are the one that works: Optus's own multi-service pricing, such as a mobile plan plus nbn on one account, is a standard advertised price rather than a personal discount, so a new nbn and a new mobile ordered through ShopBack each earn their category amount, though several SIMs on a single order earn once.

Optus prepaid starter kits are sold on optus.com.au and through Coles, Woolworths, JB Hi-Fi and Australia Post, and the supermarkets and JB Hi-Fi periodically run catalogue weeks that discount a A$30 or A$40 kit, sometimes by around half; Optus itself did not publish a starter kit discount on optus.com.au as of 2026-10-04. Only a kit bought on optus.com.au after clicking through from the ShopBack Optus page earns the Optus prepaid cashback, and it has to match a listed price point (A$39, A$40, A$49, A$59, A$180 or A$350 SIMs, eSIM included), be activated within 28 days and stay in an active recharge state for 90 days. A kit from Coles, Woolworths or JB Hi-Fi does not track as an Optus purchase on ShopBack; if those retailers' own ShopBack listings exclude SIMs and mobile services, the discount at the checkout is the whole saving. Compare the catalogue discount with the fixed Optus amount on this page before choosing.

The headline Optus windows are End of Financial Year (late June into July), Black Friday and Cyber Monday (the last Friday of November through the following Monday, 27 to 30 November in 2026) and Boxing Day, with Click Frenzy in May and November carrying smaller plan-level offers. What drops is usually the first 12 months of a plan rather than the headline price: the current pattern is a bigger data bucket at a lower monthly price for new services (such as 100GB for A$39 on the Small Choice Plus SIM) plus waived nbn setup fees or bonus data, and on handsets a bonus credit against a 24 or 36 month device repayment. Optus had not published its 2026 Black Friday pricing on optus.com.au as of 2026-10-04. Sale-price orders still earn the ShopBack amount shown on this page as long as the order starts from ShopBack and uses no code that is not listed here.

No. As of 2026-10-04 there is no discounted Optus gift card or ShopBack swap card on the ShopBack gift card hub at shopback.com.au/gift-cards, and Optus had not published a gift card product for plan payments on optus.com.au as of the same date. ShopBack also lists no Optus voucher code on this page, and ShopBack's Optus terms exclude orders that use a code not featured on ShopBack. The stack that exists is Optus's advertised promo pricing plus the fixed cashback amount for your category shown on the ShopBack Optus page.

An Optus upsize shows as an Upsized label beside the affected category (nbn, 5G Home Internet, Postpaid Mobile or Prepaid SIM) on the ShopBack Optus page and in the app, with the end date and time printed under it; as of 2026-10-04 none was running. ShopBack also surfaces live upsizes in the app's deals feed and in its email and push alerts if you have followed the Optus store, and the browser extension shows the current amount when you land on optus.com.au. Order during the window and the upsized amount is applied automatically; the tracking and 90-day confirmation rules are unchanged.
